On the webform confirmation template, these worked for me:
{{ webform_submission.webform_score.numerator }}
{{ webform_submission.webform_score.denominator }}
Yes! I can confirm dev branch fixes this issue and I'm now able to save configurations.

Just in case anyone else finds this issue, apparently you can receive this error also when trying to connect to MySQL on the wrong port number.
"PDOException: SQLSTATE[HY000]: General error: 2006 MySQL server has gone away"
